Dalal Street faces a volatile holiday-shortened week starting September 28 (Monday) and October 1 (Thursday), as investors weigh persistent foreign institutional outflows, elevated U.S. Treasury yields, and escalating oil prices driven by renewed Middle East conflict and U.S.-Iran diplomatic deadlocks.
The Nifty 50 logged its longest weekly losing streak in six years recording seven or more consecutive weekly losses only four times in the last 25 years — in 2020, 2008 and twice in 2001, with its longest losing streak being nine weeks in 2001. Ahead of a market closure on Friday for Mahatma Gandhi Jayanti, traders are navigating a hostile global macroeconomic climate where geopolitical friction directly dictates domestic risk appetite.
U.S.-Iran Tensions and the Crude Oil Price Spiral
U.S.-Iran Tensions and the Crude Oil Price Spiral
Crude oil remains the primary anchor pulling down sentiment across Dalal Street. Last week, Indian equities marked their most extended weekly slide in six years as elevated crude quotations pushed bond yields upward alongside mounting price pressures. Tensions deepened further when U.S. President Donald Trump rejected an Iranian proposal for a seven-day ceasefire and reopening of the Strait of Hormuz, stating to reporters on Saturday:
I reject this agreement. They want an agreement to be made under which the Strait of Hormuz is immediately opened, because they are severely failing.
— President Donald Trump
In response to these developments, Iranian President Masoud Pezeshkian emphasized that his nation will stand firm and refuse to back down when confronted by the United States and Israel, declaring: We stand firm with strength.
Meanwhile, Iranian Foreign Minister Abbas Araqchi posted on social media:

Our conditions are clear, and any move toward reopening the Strait of Hormuz is contingent on these conditions being met. Only a negotiated solution can get them out of this deadlock. — Iranian Foreign Minister Abbas Araqchi
Market sentiment could be impacted by any shifts in the U.S.-Iran dynamic, which directly affect crude oil valuations, the country’s import expenses, and the local currency. Trading near $105–106 per barrel, Brent crude persists at elevated levels that experts note continue to weigh negatively on the broader economic outlook. While breakthroughs in discussions between Washington and Tehran could diminish the geopolitical risk factor embedded in petroleum costs, renewed hostilities or supply interruptions might exacerbate inflationary pressures.

Foreign portfolio investors continue to pull capital from Indian exchanges even as domestic markets react to changing conditions. In addition, market watchers will keep a close eye on foreign institutional investor metrics alongside upcoming reports on monthly automobile sales.

Adding to these burdens, international financial conditions are tightening as the U.S. 10-year Treasury yield hovers near 5.2 percent, presenting an ongoing limitation for worldwide risk appetite. Overseas debt yields will also retain their significance following the Federal Reserve’s September rate decision, where further hikes in yields and the greenback might restrict emerging-market capital inflows, whereas a yield decline could offer some relief, while the domestic currency remains a critical element to observe amid steady oil-driven dollar demand and ongoing FII capital flight.

As Dalal Street looks for domestic momentum, upcoming macroeconomic releases will dictate near-term direction. Over the course of the week, the domestic calendar will feature the release of August industrial production statistics as well as the HSBC manufacturing PMI figures.
Sensex Opens Higher as Markets Track Global Cues
At the same time, Indian shares commenced Tuesday’s session on an upward trajectory, bolstered by moderating petroleum quotations and softer U.S. debt yields. Opening at 74,901.50 compared to the previous session’s finish of 74,858.99, the Sensex traded at 74,915.28—marking a gain of 56.29 points or 0.08 percent—around 9:25 am, while the Nifty opened at 23,454.05 against 23,414.30 earlier and reached 23,449.60, up 35.30 points or 0.15 percent, with all major sector gauges trading in positive territory during early exchanges.
